ERNEST PETER VINCENT, or new YORK, N. Y.

' AERONAU'TIC DEVICE.

To all whom it may concern:

Be it known that I, ERNEST Parnn VIN- earn, a sulgect of the King of Denmark, resldin at 'ew York city, in the county of New ork. and State of New York, have useful Improve following is a specification, reference being had therein to the accompanying drawing; My-invention relates to improvements in aeronautical-"devices and has particular ref erence to an aeroplane having three main supporting surfaces arranged in a staggered position. t

In the accompanying drawin I have illustrated in perspective an aeropfiine showing an a plication ofmyinvention.

Accor ing to my invention I prefer to employ three ,main supporting surfaces arranged substantially as illustrated in the drawing, the central surface being about twice as deep from front to back as the upper and lower surfaces, the upper surface extendin over the front of the centralsub face, an the lower surface extending beneath the rear of said central surface.' The preferably constructed after the manner of the main supporting surface and the frame,

work of the machine is referably mounted upon skids as shown. t will be seen that frames so mounted as to y axes, said frames containing a pair orvea tical surfaces so mounted as to swin upon. horizontal axes. From this it will e seen are capable of movement upon both vertical and horizontal axes and in addition to this the usual horizontalflsur face may be combined therewith.

4 is the upper main supporting surface 5 the central main supporting surface, an 6 the lower main supportin surface. The central main supportingjsurface may be cut away at its central portion as shown at 7 main supporting surface may be exten cd forwardly as shown at 8. With this arrangement of the supporting surfaces it will be found that they can be-placed closer together and will give a greater liftinglefl'ect atthe same time im Jroving the ossl ilities The front an elevating surface is indicated with the reference characters 3. The rear control may be entirely mounted in the rectangular frame 14 transi Specification of Letters Patent. Application fi1e d my 2a, 1910; serial No.

' 'versely of the machine and within this horizontal surframes 16 and frame may be mounted the; face 15 and the rear vertical '17 carrying the'rudder surfaces 18 and 19 respectively. The front and rear horizontal surfaces may be suitably connected by rods 9, 20'and 21 or by cable or other suitable means. The rudder surfaces 18 and 19 are also preferably connected by the rod such as 22 and the vertical frames are-also preferably connected by a rod 23. Suitable.

leys such as 24 and 25 may also be mounted in the outer frame and cords as 26 and 27 may be passed same connecting the surfaces 18 and 19 to the frames 16 and 17 respectively. A cord or wire 28 may then be connected at, the points Where the rod' 23 connects the vertical frames and by operating this cord or or Wires such through the wire it will be found that as the vertical,

frames 16 and 17 rotate in their bearings the'rudder surfaces 18 and 19,will also rotate in their bearings at right angles there fto.

Thus it will be found that when it is desired to turn the machine while in flight, the surface of the rudder will be so pre sented as to minimize "the falling tendency of the tail.

Of course it will be understood that various modifications may be made without departing from the spirit of the invention as set forth in the claims.

Having described my invention, what'I claim as new, and desire to secure by Letters Patent is: 4

In an aeroplane, three main supporting surfaces mounted upon a framework, one of said surfacesbet-ween and of greater depth from front to rear than the other of said surfaces, one of said surfaces above and the other of said surfaces below said surface of .greater depth, and said upper surface mounted over the-forward portion and said lower surface mounted beneath the rearward,

depth, a central portion cut away from said surface mounted beneath the'rearward por-.

tion of said; surface of greater depth, and

rudder surfaces being adapted to turn simultaneously upon a vert-ical'and upon a horizontal axis.

4. In an aeroplane, three main supporting surfaces mounted upon a framework, one of said surfaces between and of greater de th from front to rear than the other of said surfaces, one of said surfaces above and the other of said surfaces below said surface of greater depth, and said upper surface mounted over the forward'portion and said lower surface mounted beneath the rearward portion of said surface of greater depth, and ruddersurfaces being adapted to turn simiruiltancou'sly upon a vertical and upon a horizontal axis, in combination with a horizontal surface.

' 5. In an aeroplane, main supporting surface and three front surfaces mounted upon a framework and adapted to be rotated upon a horizontal axis, one of said front surfaces between and of greater depth from front to rear than the other of said surfaces, one of said surfaces above and the other of said surfaces below said surface of greater depth, and said upper surface mounted over the 'forward portion and said lower surface mounted beneath the rearward portion of said surface of greater depth.

6. In an aeroplane, three main supporting surfaces mounted upon a framework, one of said surfaces between and of greater-depth from front to rear than the other of said sur faces, one of saidsurfaces above and the other of said surfaces below said surface of greater depth, and said upper surface mounted over the forward portion and said lower surface mounted beneath the rearward portion of said surface of greater depth, uprights from the rear of said upper surface to the center of said surface of greater depth and to the. front of said lower surface, uprights from the front of said upper surface to the front of said surface of greater depth, and said uprights from the rear of said lower surface to the rear of saidsurface of greater depth.

7. In an aeroplane, three main supporting surfaces mount-ed upon a framework, one of said surfaces between and of/greatcr depth from front to rear than the other of said surfaces, one of said surfaces above and the other of said surfaces below said surface of greater depth, and said upper surface mounted over the forward portion and said lower surface mounted beneath the rearward portion of said surface of greater depth, uprights from the rear of said upper surface to the center of said surface of greater depth and to the front of said lower surface, uprights from the front' of said upper surface to the front of said surface of greater de'pth, and uprights from the rear of said lower surface to the rear of said surface of greater depth, and stays from the rear of said upper sitrdepth, and stays from the front of ,said lower surface to the front of said surface of greater depth.
